D-series gear pumps are precision metering pumps, particullary small and compact, that havebeen projected for the metering and dosing of great variety of fluids for chemical and plastic industries.D-series gear pumps are expressly projected for the of your products.

D-series gear pumps have only one pumping sense, standard clock wise.

The D-series inlet and outlet ports are threaded, are of the same diameter and are in-line (share the sameaxis). The flanges can be screwed.

D-series housing, covers and rotors are machined from rolled-bar that is cut, turned, machined ortoothed and in the end grinded to final shape. Using parts machined from rolled-bar instead of parts from casting,guarantee the maximum hardness allowed by the material.

The D-series can be supplied in different coupling configurations. Complete units consisting of abase-plate (not necessary for flange mounted motors), flexible coupling with guard and electric motor areavailable. 8-pole, 6-pole and 4-pole electric motors are available. Explosion proof motors, gear reducers, andvariable speed drives are also available on request.

The D-series uses a simple and versatile mechanical seal design or magnetic coupling system.

that include electric orfluid (oil or steam) heating.

One strong point of our company is the capacity of develop custom solutions, especiallycouplings solutions, in few works days. For every custom designs are available section and outline drawing,

realised with latest and updated CAD systems. In this way we can developIf our standard product can’t satisfy you request, we should project for you a special

The housing is machined from rolled bar forging that iscut, turned, machined and ground into its' finalshape, thus ensuring maximum hardness as apposedto using cast parts.

Gear and shaft are machined from rolled-bar that iscut, turned, toothed and grinded to final shape.Using parts machined from rolled-bar instead of partsfrom casting, guarantee the maximum hardnessallowed by the material.

the plates are .Nitrurated

To prevent leakage, any parts of the pump housingmatch the other with O-Rings seated between thetwo faces to guarantee sealing also in presence oflow viscosity medium. Note that on D18 seal coverare used Plane gasket (13). According to API610 andPLAN13, shaft seal is ensured by one external lip sealand one mechanical seal.

TITANIUM NITRIDE COATING(TiN)

NITRIDING PROCESSObjective of nitriding is to increase the hardness of thecomponent’s surface by enriching it with the diffuson ofnitrogen atoms into the metal’s surface. Nitrogen is acolorless, odorless, tasteless and inert diatomic gas,constituting 78.1% by volume of Earth's atmosphere.

Titanium Nitride (TiN) is the most commonhard coating in use today. TiN has anexcellent combination of performanceproperties as:+Wear resistance and extremehardness, is harder than carbide.+Maintaining sharp edges or corners+Prevent galling, and decreasesfriction.+Resistant to nearly all chemicalsand also withstands hightemperatures .

The standard mechanical seal can

be replaced by a systemthat definitively eliminates seal leakage andwear in particularly harsh conditions.Magnetic coupling are synchronous couplingthat transmits torque through magnetic forcesbetween the internal and external rotor, butensures a hermetic separation of the drive and

the driven side via bell.
